Why is Pd often "better" at C-H activation than Ni? Just published in JACS, we show that Pd acidifies C(sp3)-H bonds 100,000 times more than Ni. Our DFT collab with @tkschramm.bsky.social and Andreas Hansen @unibonn.bsky.social was crucial to explain acid-base rxns!

Thanks for two great talks in the SFB 1633 Seminar Series recently:
-Prof. Dr. Katja Heinze: Photochemistry of Complexes with Earth-abundant Metals
-Prof. Dr. Charles Machan: Metal-Free Molecules as Electrocatalysts and Co-electrocatalysts
Excited for two more talks coming up!

Mechanism of catalyst activation in iron(porphyrin)-catalysed aerobic oxidative cleavage of 2,3-dimethylindole Ferric porphyrins catalyse the aerobic oxidative cleavage of 2,3-dimethylindole, mimicking dioxygenase enzymes. The data herein suggest that the indole reduces the FeIII(porphyrin) to FeII(porphyrin) ...

I'm excited to share the first publication out of the Brezny lab! We explored some unexpected reactivity of an indole with metalloporphyrins. Thank you to all my awesome students that contributed to this work.

Made the trek to Nuremberg today and rediscovered my sweet tooth!

Franconian house from the 1700s

Franconian wooden ceiling

Renovated half-timbered Franconian house from 1700s in downtown Erlangen. When the style went out of fashion, wooden spikes were embedded to support plaster over the entire wall. Times have changed again! Note the Franconian wooden ceiling.

I made it! Here is the home of Inorganic at FAU where they will graciously let me fumble around. Guesthouse is across the street, shortest work commute I have had in a while!

I’m waiting for take off in CHO on first leg to Germany. I’ll be at FAU Erlangen-Nürnberg for the better part of a year! Looking forward to the adventure and the family joining for Christmas in a month!

Chemical Hearth - American Chemical Society The Rotunda, a University of Virginia building designed by Thomas Jefferson, burned down in an 1895 fire, but an important, hidden part of the Rotunda survived: a chemical hearth.

There’s been an update to the ACS website for the upcoming dedication the UVA rotunda! Read about some of the early history of chemical education that led to the chemistry department here.
